' To all whom it may concern: l

Be it known that I, PAUL F. Busen, citizen of thevUnited States,residing 'at-Cleve- 'of Ghio, have invented certain new and usefullinproveinents in Grain-Doors for lGars, of which the following is aspeclcation.

My invention rela-tes to an improvement in doors .for grain'ca-rs, allsubstantially as shown and described and-.particularly pointed butinth'elelaiins.

'I ln the accompanying drawings,v Figure l 1 Visfar side elevation of aear embodying iny inention, -and Fig. 2 is an enlarged cross section.Fig. 3 isfa plan of the immediate eontrolling means for the doors, andFig. 4 is a perspective viewof one of the doors and of the controlling-meansA in working relations therewith. `Fig. 5 is a plan View of one ofthe quadrangu'lar posts and a 'section of a door therein. 1 The leadingidea'of provide a tiexible door for grain cars adaptway when not wanted.provide a door D for each side of the car ed to'slide in guidewaysvatthe edges ot' the door 'opening and extending beneath the car so astorun said'doors down out of the To these ends l C, and this door issupplemental to the usual outside sliding door B., The said door D isconstructed from a series of corresponding slats or pieces 2 otsheetmetal provided eaeh with an otlset,k portion 3 at what becomes the innerupper edge, said oset portion having a right angled shoulder of a depthequal to the thickness of said strip so as to make a plain and smoothinterior adapted to eonline the grain at the saine time that -the doorVor gate will flex to turn the angle oi curve which will bring it beneaththe ear. At further peculiarity of the construction of this door` is thehinges l which connect the l slats or plates Q, said hinges beingprovided near the two ends of the slats on the inside opposite the saidoffsets 3. lt follows that the said doors can bend or flex in making theturn beneath the car but lie perfectly dat one against one another insaid otliset por tion when up in using position, This ot course atl'ordsthe desired closure tor grain and enables either door to be opened moreor less or raised more or less when a ear is being tilled'with grain andalso to be lowered and run entirely out of the way when.

the inventionis to lsary room for storing saine.

thejcar is unloaded or when it is used for other purposes. v One of thematerial advantages of this airangement of doors, or 'construction ofear, is that when they grain is stowed away out ofuse it is out of theWay in every respect and leaves the car with its full caf paeityand-room to receive any other coniinodity than grain up to the roof. Theguides or runways for said doors are shown as substantially squaresectioned or four sided posts or boxes b, which extend down to thebottoni of the car in this or equivalent forni and are supplementedbeneath the ear by the bottoni b as seen in Figvl. Each slat or plate isfurther provided with 4a seetion 5 of what becomes as a whole a toothed.raek R upon the inside of each door at the. edge thereof, and these racksections. run in the said guide boxes or'ways b and confine the gatelaterally as to said parts. Y

l) represents a pinion engaged with each of Vsaid racks,V` in the anglewhere door D runs beneath the Ifloor of the car ontol guideway orsupport o beneath, and the said guideways ZJ for the opposite doorsoverlap beneath the ear so as to provide the neces- Said pinions aremounted on a shaft S transversely of the 'door opening anda bevel gear Gthereon is nieshed by a corresponding gear G on a hand actuated shaft Swhich is located at one side of the door and practically out ot the wayand has a hand wheel H for controlling saine. The pinions P mesh withthe racks R and serve to operate the door D both ways. Respecting thesaid door or doors, it is to be further observed that there a skip oropening in the lower portion thereof or between the so-called lower slatl0 ot the door series proper and the end slat l2 while the rack Rcontinues across said skip or opening on a flexible steel strap llconnecting said slats l0 and l2 at its ends.' The said opening is usefulonly in unloading or emptying a car iilled with grain' or other likeiiowing material. and is inade available for this purpose. ,Theseguidesl extend upward 'within the ear relatively to the toptliereoifr.,as seen in Fig. 2, wherein the door D also has been run uplto its limit and the "opening O- therein is exposed at the bottom inFig. 4, or at the left, Fig. 2, and in which said case it is at leastabove the highest filling level of lthe grain in the car.

7What I claim is:

.1. A oar having a door opening in its side 'and a guidewa)Y for thedoorbeneath the car communicating with said opening, said door havingl aflexible toothed rack on its inside along each edge and extending belowthe lower edge ofthe door, a shaft having p'inions located in the anglebetween said guideivay and-said door opening, and a hand con- 4trolledshaft for controlling the door, whereeach side having sectionscorresponding to said-slats, guideways for said door extending beneaththe car body, pinions in operating engagement 'with said racks and handcontrolled means to operate said pinions and raise and lovver the door,the said racks eX- tending beyond the. lower edge of the door andflexible straps supporting said extengrain door consisting of a. seriesof slatsv hinged together and extendingl into said guidewavs and slatprovided with a section of a continuons toothed rack confined withinsaid guideways, a shaft at the bottom of said' door opening havingpinions meshing with said racks and a gear on one end, and a handcontrolled gear meshing with said gear and adapted to-operate said door.

In testimony whereof I aflix my signature in presence of two witnesses.

PAUL F. BUSCH.
